The college grounds stretch north and east from the college, and include most of the area bounded by Longwall Street, the High Street (where the porter's lodge is located), and St Clement's. The college features a variety of architectural styles, and has been described as "a medieval nucleus with two incomplete additions, one from the eighteenth and one from the nineteenth century".
The college is organised around five quads. The irregularly shaped St John's Quad is the first on entering the college, and includes the Outdoor Pulpit and old Grammar Hall. It connects to the Great Quad (the Cloister) via the Perpendicular Gothic Founders Tower, which is richly decorated with carvings and pinnacles and has carved bosses in its vault. The Chaplain's Quad runs along the side of the Chapel and Hall, to the foot of the Great Tower. St Swithun's Quad and Longwall Quad (which contains the Library) date from the late 19th and early 20th centuries, and make up the southwest corner of the college.
